Discretionary power of project managers in knowledge intensive firms and gender issues

The scarcity of women among the highly qualified professionals in business-to-business information and communication technologies (ICT), either in Europe andor in North America, has been noted as recently as the late 1990’s (Panteli, Stack, Atkinson, & Ramsay, 1999). The organization and management of work in such organizations firms is typically project-based. This has many consequences, including: long working hours with fierce resistance to shorter hoursany reduction, unpaid overtime, high management expectations of employee flexibility to meet unanticipated client demands, and the need for employees to negotiate flexible work arrangements on a case-by-cases basis with a project manager who often has much discretion on whether to accommodate such requests. We found that women are particularly disadvantaged in such a system, which could partly explain their under-representation in such jobs

Employee trust and workplace performance

We explore the relationship between employee trust of managers and workplace performance. We present a theoretical framework which serves to establish a link between employee trust and firm performance as well as to identify possible mechanisms through which the relationship may operate. We then analyse matched workplace and employee data in order to ascertain whether the average level of employee trust within the workplace influences workplace performance. We exploit the 2004 and 2011 Workplace Employment Relations Surveys (WERS) to analyse the role of average employee trust in influencing workplace performance in both pre- and post-recessionary periods. Our empirical findings support a positive relationship between three measures of workplace performance (financial performance, labour productivity and product or service quality) and average employee trust at both points in time. Moreover, this relationship holds when we jointly model average employee trust and firm performance in an instrumental variable framework in order to take into account the potential endogeneity of employee trust. We then exploit employee level data from the WERS to ascertain how individual level trust of the employee (rather than the average within the workplace) is influenced by measures taken by employers to deal with the recent recession. Our findings suggest that restricting paid overtime and access to training potentially erode employee trust. In addition, we find that job or work reorganisation experienced at either the employee or organisation level is associated with lower employee trust

Applying an extended theoretical framework for data collection mode to health services research

<p>Abstract</p> <p>Background</p> <p>Over the last 30 years options for collecting self-reported data in health surveys and questionnaires have increased with technological advances. However, mode of data collection such as face-to-face interview or telephone interview can affect how individuals respond to questionnaires. This paper adapts a framework for understanding mode effects on response quality and applies it to a health research context.</p> <p>Discussion</p> <p>Data collection modes are distinguished by key features (whether the survey is self- or interviewer-administered, whether or not it is conducted by telephone, whether or not it is computerised, whether it is presented visually or aurally). Psychological appraisal of the survey request will initially entail factors such as the cognitive burden upon the respondent as well as more general considerations about participation. Subsequent psychological response processes will further determine how features of the data collection mode impact upon the quality of response provided. Additional antecedent factors which may further interact with the response generation process are also discussed. These include features of the construct being measured such as sensitivity, and of the respondent themselves (e.g. their socio-demographic characteristics). How features of this framework relate to health research is illustrated by example.</p> <p>Summary</p> <p>Mode features can affect response quality. Much existing evidence has a broad social sciences research base but is of importance to health research. Approaches to managing mode feature effects are discussed. Greater consideration must be given to how features of different data collection approaches affect response from participants in studies. Study reports should better clarify such features rather than rely upon global descriptions of data collection mode.</p

Impact of SO2 and bentonite addition during fermentation on volatile profile of two varietal white wines

To understand the impact of SO2 and ascorbic acid (AA) in must fermentation, Arinto and Síria musts were fermented under the same conditions, but in the presence of different doses of SO2 and with or without bentonite addition. Arinto was fermented with 0, 50, 100 mg/L of SO2 and 100mg/L of AA. Síria was fermented with 0, 15, 30, 45 mg/L of SO2 and 100 mg/L of AA. The volatile organic compounds (VOCs) were analysed by HS-SPME-GC/MS. Based on PCA results obtained from VOCs profiles for both varieties, first and second principal components were responsible for more than 60% of the respective system´s variance. In both wines, the presence or absence of bentonite was clearly discriminated. This work also shows that depending on the different doses of SO2 used, the resulting VOC profiles clearly discriminate these different fermentation conditions. The use of AA in both varieties resulted in a different VOC profile compared to the use of SO2. From this study It was also possible to verify from the VOCs profile, that Arinto wine is less resilient to fermentation changes then Síria wine, which may impact technological choice
